IDT5V9885T  
3.3V EEPROM  
PROGRAMMABLE CLOCK  
GENERATOR  
FEATURES:  
DESCRIPTION:  
• Three internal PLLs  
TheIDT5V9885Tisaprogrammableclockgeneratorintendedforhigh  
performancedata-communications,telecommunications,consumer,and  
networking applications. There are three internal PLLs, each individually  
programmable,allowingforthreeuniquenon-integer-relatedfrequencies.  
The frequencies are generated from a single reference clock. The  
reference clock can come from one of the two redundant clock inputs. A  
glitchless automatic or manual switchover function allows any one of the  
redundant clocks to be selected during normal operation.  
• Internal non-volatile EEPROM  
• JTAG and FAST mode I2C serial interfaces  
• Input Frequency Ranges: 1MHz to 400MHz  
• Output Frequency Ranges: 4.9kHz to 500MHz  
• Reference Crystal Input with programmable oscillator gain and  
programmable linear load capacitance  
Crystal Frequency Range: 8MHz to 50MHz  
• Each PLL has an 8-bit pre-scaler and a 12-bit feedback-divider  
• 10-bit post-divider blocks  
The IDT5V9885T can be programmed through the use of the I2C or  
JTAG interfaces. The programming interface enables the device to be  
programmedwhenitisinnormaloperationorwhatiscommonlyknownas  
in-system programmable. An internal EEPROM allows the user to save  
and restore the configuration of the device without having to reprogram it  
on power-up. JTAG boundary scan is also implemented.  
• Fractional Dividers  
• Two of the PLLs support Spread Spectrum Generation  
capability  
• I/O Standards:  
Outputs - 3.3V LVTTL/ LVCMOS, LVPECL, and LVDS  
Inputs - 3.3V LVTTL/ LVCMOS  
Each of the three PLLs has an 8-bit pre-scaler and a 12-bit feedback  
divider. Thisallowstheusertogeneratethreeuniquenon-integer-related  
frequencies. The PLL loop bandwidth is programmable to allow the user  
totailorthePLLresponsetotheapplication. Forinstance,theusercantune  
the PLL parameters to minimize jitter generation or to maximize jitter  
attenuation. Spread spectrum generation and fractional divides are  
allowed on two of the PLLs.  
• Programmable Slew Rate Control  
• Programmable Loop Bandwidth Settings  
• Programmable output inversion to reduce bimodal jitter  
• Redundant clock inputs with glitchless auto and manual  
switchover options  
• JTAG Boundary Scan  
• Individual output enable/disable  
• Power-down mode  
Thereare10-bitpostdividersonfiveofthesixoutputbanks. Twoofthe  
six output banks are configurable to be LVTTL, LVPECL, or LVDS. The  
otherfouroutputbanksareLVTTL. TheoutputsareconnectedtothePLLs  
via the switch matrix. The switch matrix allows the user to route the PLL  
outputstoanyoutputbank. Thisfeaturecanbeusedtosimplifyandoptimize  
the board layout. In addition, each output's slew rate and enable/disable  
function can be programmed.  
• 3.3VVDD  
• Available in TQFP and VFQFPN packages
